APPLICATIONS OF WINGTACK® RESINS. ................................................................... 10

3

Wingtack® hydrocarbon resins are synthetic resinsobtained by cationic polymerization of aliphatic mono-mers (C5). WINGTACK® is used in Pressure Sensi-tive Adhesives (PSA) as tackifying resin and in HotMelt Adhesive (HMA).

Because of their unique chemistry WINGTACK®

resins show outstanding properties:· Uniformity and consistency· Light color

· Low odour· High tack properties· Low specific gravity· Oxidative stability· Very low chloride levels

Wingtack® resins are also used as tackifying resins and/or “processing aids” (improvement of compounding,extrusion and molding properties) of EPDM, SBR,Polyisoprene, SIS, Butyl rubber based compounds,depending on their compatibility.

Isoprene compatible

Increasing Butadiene compatibility

Wingtack® resins are available having a variety of dif-ferent physical and chemical properties (like softeningpoint, glass transition temperature and molecular weightdistribution) each effecting the performance of the sys-tem as well as compatibility with various polymers andelastomers.

The two primary catagories of Wingtack® resins are1) aliphatic and 2) aromatically modified aliphaticresins.

1) Pure aliphatic resins:

Resin Type

Wingtack® 10 Liquid resin used as plasticizer. Better bleed resistance than oils.

Wingtack® 98 Designed for standard applications like packaging and masking tapes.

Wingtack® 95 Ideal for high performance applications in less polar elastomers (NR, SIS) and waxes.

Wingtack® RWT-7850 High softening point resin. Excellent for broad range of uses.

2) Aromatic-modified aliphatic resins:

Resin Type

Wingtack® PLUS Narrow molecular weight distribution. Best resin for use in SIS based high performance formulations.

Wingtack® EXTRA Good general purpose resin.

Wingtack® ET Low molecular weight and higher aromaticity for improved EVA and Butadiene compatibility. Partial replacement for Hydrogenated resins.

Wingtack® STS Medium softening point and broad range of compatibilities including SIS, SBS, SBR, SIBS and EVA.

Wingtack® 86 Low softening point resin. Broad range of compatibilities including SIS, SBS, SBR, SIBS and EVA.

Packaging and storage

Packaging: Wingtack® 10 liquid resin is packaged in4x172kg drums on wood pallet ( 689 kg ). Wingtack®

solid resins are packaged in 25kg paper bags, 45bags on wood pallet ( 1125kg).

Storage : all resins with a low softening point present arisk of solidifying, which increases in hot weather.Therefore, for softening points of less or equal to100°C, we recommend : storage in a cool ( 25 °Cmax ), ventilated area, out of the sunlight; do not stackpallets; avoid storage for prolonged period.

Wingtack 86 : due to low softening point, seriousremassing of product may occur when exposed toelevated temperatures. Customer accepts theresponsibility for using remassed material.
